🧠 About IQ Spark

IQ Spark is a free online intelligence assessment tool designed to measure your cognitive abilities through pattern recognition tasks. Our test is based on the scientifically validated Raven's Progressive Matrices methodology, which has been used worldwide since 1936.

We believe that understanding your cognitive strengths should be accessible to everyone, which is why our test is completely free with no hidden costs or premium features locked behind paywalls.

Raven's Progressive Matrices was developed by English psychologist John C. Raven to measure the reasoning aspect of general intelligence (known as Spearman's "g"). The test consists of visual geometric patterns with a missing piece, and test-takers must identify the correct piece from multiple options.

This type of test measures fluid intelligence (Gf) – the ability to think logically and solve problems in novel situations, independent of acquired knowledge. Research has shown that matrix reasoning tests are among the best single indicators of general cognitive ability.

Our test includes 36 questions divided into three sets of increasing difficulty:

• Set A (Questions 1-12): Basic pattern completion
• Set B (Questions 13-24): Analogical reasoning
• Set C (Questions 25-36): Abstract reasoning with complex rules

Your IQ score is calculated using the Wechsler scale, where the average score is set at 100 with a standard deviation of 15. This means:

• About 68% of people score between 85-115
• About 95% of people score between 70-130
• Only 2% of people score above 130 (Very Superior)

We also provide age-adjusted scoring to account for the natural changes in fluid intelligence across the lifespan. Research shows that fluid intelligence typically peaks in early adulthood and gradually declines with age.

While IQ Spark provides a scientifically-based estimate of your cognitive abilities, it is designed for educational and entertainment purposes only. For official IQ assessment, clinical diagnosis, or educational placement decisions, please consult a licensed psychologist who can administer a comprehensive, standardized IQ test.

Factors such as fatigue, stress, or distraction can affect your test performance. For the most accurate results, take the test in a quiet environment when you are well-rested and focused.
